BUCKLE.

Application filed October 29, 1928. Serial No. 315,64.

'.lhis invention relates to a buckle for fastelling the ends of a wrist strap more par? ticularly ci the type for securing a wristl watch in position on thearm ot the wearer; and has 'l'cr its obyect to provide a .com

struction for easily attaching and detach-` :ing its members by thesingle available hand oit the wearer of the strap. i

A further object ot the invention is the provision of a buckle in which the construction for holding the parts together are hidden by a cover so that the buckle may be of a more attractive appearance or suitably decorated upon the surface presented.

ldith these and other objects in view, the invention consists of certain novel 'features ot' construction, as will be more fully der scribed, and particularly pointed out in the appended claims.

lin the accompanying drawings:

Fig. 1 is a top plan View of the two part strap 'withA my buckle in position thereon.

Fig. 2 is a side elevation oi' the buckle with portions of the strap attached thereto.

Fig. 3 is a perspective view looking at the under side of the cover member.

Fig. l is a perspective view of the plate which has openings to receive the detents of the male part of the buckle member.

Fig. 5 is a perspective view looking at the underside of the male buckle member with the parts shown in Figs. 3 and 4l assembled.

Fig. 6 is a perspective view of one part of the male buckle member.

Fig. 7 is a perspective View of the under side of the male buckle member showing the strap clamp thereon.

Fig. 8 is a sectional view of the two buckle members in clasped position.

This invention is an improvement of my copending application, Ser. No. 274,236, filed `lli/lay 1, 19287 and by my new construction the ifemale member of the buckle which has a plate with openings therein to receive the det-ents of the male buckle member is hidden by a cover which presents a very attractive appearance and by means of flanges on the cover this member may be guided and more easily snapped into position over the male member and detached by means of the finger-piece which also holds the parts in position and the following is a detailed description of the present embodiment ot this invention illustrating the pre Vas at -23 extending therefrom.

ferred means by which these advantageous results are accomplished:

in the sidewalls by trunnions 17.

The lemale member oit this buckle forms a tip for this strap part 12 and `consists of a plate 13 having openings 19 therein suitably cut away as at 2O to allow resiliency of its side wall for snapping over the detents 14- of the male member to hold the buckle members together. A cover, as illustrated in Fig. 3, is provided for this plate which has a sheet metal top 21 with side flanges 24 and an end flange 22 slotted The plate 1S is provided with a finger-piece 25 which extends thru the slot 23 to hold the same in position. This slot is" spaced slightly from the sheet metal top wall which" is accurately shaped to form a space for the reception of the detents 111 when snapped thru the plate openings 19.

The plate is offset as at 2G so that a portion 27 will lie snugly against the top plate 21 at its other end, which portion. receives the end 28 of the strap 12 to be clamped in this position by means ot arms 29 extending from the cover and folded inwardly about this strap end 28. These arms have teeth 3() thereon to bite into and hold the strap in position. The offset of the plate as at 2G also provides a stop to limit the insertion of the strap 12 and assists in the assembly of the strap and buckle in the manufacture of the same.

A ilange 32 may be provided at the strap engaging end of the cover to assist in hold ing the strap in position and at the same time providing the buckle with a more linished appearance and serving to prevent a sliding movement of the plate from its position in the slot 23.

Further, in order that a proper point of bending of the arms may be provided, flanges 31 extend from the ol'set portion of the plate over which the arms are bent into their' biting and embracing relationwith the strap.

It Will bey apparent from the above that the tWo part bucklewhich I have provided isof a construction to present an extended surface or ornamentation -Wthout the visii ble openings or projections thru a plate to one car ied by each of the strap parts, one

member being adjustably secured to one strap part and the other member being secured to the end of the other strap part and comprising a plate, cooperating means between said first member and plate for releasably locking them together, a sheet metal cover for said plate, langes extendin r from said cover, one flange having a slot t lei-ein,

a projection on said plate extending thru said slot to serve as a finger-piece for separating said member and also to hohl said plate in position in said sheet metal cover.

2. A separable buckle for separable strap parts, comprising two cooperating members, Aone carried by each of said strap parts, one member being,r adjustably secured to one. strap part and the other member secured to the end of the other strap part and comprising a sheet metal cover having an end flange with a slot therein, a plate within said eover spaced therefrom adjacent to sa id flange and oifset to lie against said cover at its other end to receive on said offset portion the strap to which it is connected, and a lingerpiece extending from said plate thru said slot to hold the plate in said spaced relation. In testimony whereof I afiix my signature.
